Graviton
Graviton 5V-48V Relay UPS Power-Off Module
A 5 V to 48 V relay module that automatically switches a load to backup power when the main DC supply fails
- Wide input range 5V to 48V fits many DC sources
- Automatic switchover keeps load powered when main supply fails
- Emergency cut-off protects connected equipment during faults
- Charges backup cell while main power is present
- Customisable voltage regulator suits computer applications
Power Range and Function
This Graviton relay module manages automatic power switching between a DC input and a backup source for computer applications. It operates across a 5V to 48V supply range and prefers the DC terminal when power is present. The module handles the changeover to the alternative supply when the primary DC source fails.
Builders Needing Automated Failover
The module suits engineers adding emergency cut-off or UPS-style switching to custom electronics projects. It is not for users requiring a complete uninterruptible power supply with integrated batteries or charging circuitry. Buyers who need detailed electrical specifications beyond the voltage span should look elsewhere.
5V to 48V Operating Window
The single specification that decides fit is the 5V to 48V supply voltage range. Your primary DC source and backup source must both fall within these limits for the automatic switching to function correctly. Verify your system voltages match this window before purchasing.

Questions about this item
Will this module switch my existing 48V backup battery to the load automatically when the main DC supply fails?
Yes, it automatically switches to power the load when there is no power at the DC terminal, supporting supply voltages up to 48V.
How can I verify the automatic switching is functioning correctly after installation?
Remove power from the DC input terminal and confirm the load remains powered by the backup source without interruption.
Does the package include the battery or power supply, or must I source those separately?
Only the relay module board is included; you must provide your own DC power supply and energy storage device separately.
